Low-frequency sleep – electromagnetic

Posted under: Military, Science, Technical, Weapon

From 1980 to 1983, a man named Eldon Byrd ran the Marine Corps Nonlethal Electromagnetic Weapons project. He conducted most of his research at the Armed Forces Radiobiology Research Institute in Bethesda, Md. “We were looking at electrical activity in the brain and how to influence it,” he says. Byrd, a specialist in medical engineering and bioeffects, funded small research projects, including a paper on vortex weapons by Obolensky. He conducted experiments on animals–and even on himself–to see if brain waves would move into sync with waves impinging on them from the outside. (He found that they would, but the effect was short lived.)

Owen Machine Carbine

Posted under: Machine, Science, Technical, Weapon

The Owen Gun, which was known officially as the Owen Machine Carbine, was an Australian submachine gun designed by Evelyn (Evo) Owen in 1939. The Owen was the only Australian-designed service firearm of World War II and was the main submachine gun used by the Australian Army during the war.

Owen, an inventor from Wollongong, was 24 in July 1939 when he demonstrated his prototype .22 calibre “Machine Carbine” to Australian Army ordnance officers at Victoria Barracks in Sydney. The gun was rejected because the army, at the time, did not recognize the value of submachine guns. Following the outbreak of war, Owen joined the army as a private.

Laser

Posted under: Science, Technical, Weapon

A ‘laser range-finder’ is a device which uses a laser beam in order to determine the distance to a reflective object. The most common form of laser range-finder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used.
